@ingroup hash

Compute the distance between 2 hashcodes. The computation must be fast, not involve @a a[0] or @a a[4] (they’re used elsewhere), and be somewhat consistent. And of course, the result should be a positive number.

@param a some hash code @param b some hash code @return number between 0 and UINT32_MAX
